Notoryctidae
Notoryctidae is a family of mammals, allying several extant and fossil species of Australia. The group appear to have diverged from other marsupials at an early stage and are highly specialised to foraging through loose sand; the unusual features have seen the unique family placed in the taxonomic order Notoryctemorphia Aplin & Archer, 1987. The eyes and external ears are absent in the modern species, the nose is shielded and mouth reduced in size, and they use pairs of well developed claws to move beneath the sand. The Australian animals resemble a species known as moles, a burrow building mammal found in other continents, and were collectively referred to as 'marsupial moles'. The regional names for the well known animals, established before their published descriptions, are used to refer to the species. The extant notoryctid species are subterranean, and are extremely well adapted to moving through sand plains and dunes, these are the two species of genus ''Notoryctes'' Stirli ...

Notoryctes Typhlops
The southern marsupial mole (''Notoryctes typhlops''), also known as the itjaritjari () or itjari-itjari, is a mole-like marsupial found in the western central deserts of Australia. It is extremely adapted to a burrowing way of life. It has large, shovel-like forepaws and silky fur, which helps it move easily. It also lacks complete eyes as it has little need for them. It feeds on earthworms and larvae. History of discovery Although the southern marsupial mole was probably known by Aboriginal Australians for thousands of years, the first specimen examined by the scientific community was collected in 1888. Stockman W. Coulthard made the discovery on Idracowra Pastoral Lease in the Northern Territory by following some unusual prints that lead him to the animal lying under a tussock. Not knowing what to do with the strange creature, he wrapped it in a kerosene soaked rag, placed it in a revolver cartridge box and forwarded it to E. C. Stirling, the Director of the South Australia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kakarratul
The northern marsupial mole or kakarratul (''Notoryctes caurinus'') is a marsupial in the family Notoryctidae, an endemic animal of arid regions of Central Australia. It lives in the loose sand of dunes and river plains in the desert, spending nearly its entire life beneath ground. The facial features are reduced or absent, their small and strong body, weighing little more the 30 grams (1 ounce), is extremely specialised to moving through sand in search of prey. The species is elusive and it is one of the most poorly understood mammals of Australia. Taxonomy A description of the species was published by Oldfield Thomas in 1920. One of two extant species of the genus ''Notoryctes'', following recognition of its separation from ''Notoryctes typhlops'' in 1988. The specimen described by Thomas was collected in 1910 by a postal official at Wollal, at Ninety Mile Beach in north-western Australia, and this was conveyed to the Western Australian Museum. Thomas distinguished the new sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Notoryctes
Marsupial moles, the Notoryctidae , are highly specialized marsupial mammals, known from two species found at the Australian interior. * ''Notoryctes typhlops'' (southern marsupial mole, known as the ''itjaritjari'' by the Pitjantjatjara and Yankunytjatjara people in Central Australia). * ''Notoryctes caurinus'' (northern marsupial mole, also known as the ''kakarratul'') Notoryctids are small, fossorial mammals that anatomically converge on other fossorial (and distantly related) mammals, such as living golden moles (Chrysochloridae) and extinct epoicotheres (Pholidota). Characteristics In an example of convergent evolution, notoryctids resemble (and fill the ecological niche of) moles from North America and Eurasia and golden moles from Southern Africa. Like chrysochlorids and epoicotheres, notoryctids use their forelimbs and enlarged central claws to dig in a parasagittal (i.e., up and down) plane, as opposed to the "lateral scratch" style of digging that characterizes talpi ...

Naraboryctes
''Naraboryctes philcreaseri'' is a fossil species of marsupial found at early Miocene deposits of Boodjamulla National Park of Riversleigh area, northwestern Queensland, Australia. Taxonomy It was first named by Michael Archer, Robin Beck, Miranda Gott, Suzanne Hand, Henk Godthelp and Karen Black in 2011 and is the type species of genus ''Naraboryctes''. The generic name means "to drink" (naraba in Garrawa and Waanyi languages of northwestern Queensland) in reference to its rainforest palaeohabitat + "digger" (oryctes in Greek) in reference to its fossorial specializations and close relationship to the extant species of genus ''Notoryctes''. The specific epithet honors Phil Creaser, and is referred to as "Phil Creaser's Drinking Digger". The genus is allied to the family of modern 'marsupial moles', Notoryctidae, two or three species of the extant genus ''Notoryctes''. However, a more recent study showscases that it lacked many of the synapomorphies associated with marsupial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marsupial
Marsupials are any members of the mammalian infraclass Marsupialia. All extant marsupials are endemic to Australasia, Wallacea and the Americas. A distinctive characteristic common to most of these species is that the young are carried in a pouch. Marsupials include opossums, Tasmanian devils, kangaroos, koalas, wombats, wallabies, bandicoots, and the extinct thylacine. Marsupials represent the clade originating from the last common ancestor of extant metatherians, the group containing all mammals more closely related to marsupials than to placentals. They give birth to relatively undeveloped young that often reside in a pouch located on their mothers' abdomen for a certain amount of time. Close to 70% of the 334 extant species occur on the Australian continent (the mainland, Tasmania, New Guinea and nearby islands). The remaining 30% are found in the Americas—primarily in South America, thirteen in Central America, and one species, the Virginia opossum, in North America, n ...

Dental Formula
Dentition pertains to the development of teeth and their arrangement in the mouth. In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. That is, the number, type, and morpho-physiology (that is, the relationship between the shape and form of the tooth in question and its inferred function) of the teeth of an animal. Animals whose teeth are all of the same type, such as most non-mammalian vertebrates, are said to have '' homodont'' dentition, whereas those whose teeth differ morphologically are said to have '' heterodont'' dentition. The dentition of animals with two successions of teeth (deciduous, permanent) is referred to as '' diphyodont'', while the dentition of animals with only one set of teeth throughout life is ''monophyodont''. The dentition of animals in which the teeth are continuously discarded and replaced throughout life is termed ''polyphyodont''. The dentition of animals in which the teeth are set in s ...

Taxa Named By James Douglas Ogilby
In biology, a taxon (back-formation In etymology, back-formation is the process or result of creating a new word via inflection, typically by removing or substituting actual or supposed affixes from a lexical item, in a way that expands the number of lexemes associated with the ... from ''Taxonomy (biology), taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular Taxonomic rank, ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
